Steal this idea: G+ public hangouts

So, Google Hangouts are actually fun. They can also be made public. A rather interesting application of plus might be doing some conscious people-surfing, by talking to named strangers who make themselves thusly available.

There doesn't seem to be a way, however, to list all of the public hangouts currently open on the whole network. Relatively easy to fix (with some minor reverse-engineering). Gladly volunteer as a beta tester :)
